Specication of Letters Batent No. 26,490, dated' Deceinbeiikz,

To all` whom it may concern: .i y y Be it known that we, Gr. GooDALE and R. L. T. MARSH, both of Centralia, in the county of Marion and State of Illinois, have invented a new and ImprovedJSteamfExcavator; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part `of this specication, in whichy i Figure l, is a side elevation ofiour invention. Fig. 2, is a transverse vertical section of the same, taken in the line na?, Fig. 3. Fig. 8, isa plan ortop `view ofthe same. Fig. 4c, is a detached perspective view of a turn table. y i i Similar letters of reference indicate corresponding parts in the several figures.`

This invention consists-lst. In the combination with a locomotive steainengine of an excavating wheel and suitable earth receptacles in such a manner that the machine will be pro elled over the ground, under the guidance o the attendant, to the spot tobe excavated, then load itself with earth and carry the load to the desired place for discharge as hereinafter set forth. 2nd.` In the combination with an excavating machine as above described of an exterior rail road track in the manner to be hereinafter set forth, so that the earth as fast as it is lifted by the wheel may be received within the suitable` cars to be transported upon the track to other parts of the machine. 3rd. In the combination with said track ofturn tables so that the cars may be made to pass around the corners of the machine as hereinafter set forth. 4th. In making the journals ofthe excavator adjustable so that it can be raised or lowered at will.

To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it. i H

A, represents a rectangular frame which is mounted on wheels B, B, C, C,`the front wheels B, B, having their axle a, secured to the `frame by a king bolt Zn To the axle a,

a segment rack o, is attached and into this rack a pinion d, gears, said pinion being on the lower end of a vertical shaft e, which has a bevel pinion f, on its upper end into which a corresponding pinion g, gears, the pinion g, being on the shaft it, of a hand wheel D. The back wheels C, C, are broad and have projecting spurs or plates z', on them, said plates extending the whole width of the OFFICE- wheels C, and prevcntingtlie same, said wheels beingpthedriving wheelslw i ofthe mzwhne.` i i y y The axle E; O-fthe wheels!GstCilieeef` toothedwheelax, oniit andtheinner side `of each wheel C.,f ha`sliaptoct1iedri1n l", attached Sadfims swells mtv `nnions` one Shaftflis, which has two cranks jalo, `ong it, loneicltank i i being et right angle/Site@ the `when To each crank a connecting` rodlfl, isf` aittachdwand i to each rod Z, a pistonrcdm, is connected, w

On therifraineA, ,at about itsycenterya :1 shaft G, is placed .transversely..` This shaft "1V has itsjournals ttwedin bearings n, n, `which y on standards H, `Eachlbearing n/,islconw` y g. To one end of thezshaft; G, an elevator` .Lis with radial buckets?,iasrshownc earlyfin if are allowed to slidevertically between guides nected by a chain o., withal shaft-1.1, which some distanceabove the shaft G, see `Fi attached. This elevator is azwheel rovided Figs. 1 and 2, thebuckets.beingatthe side` of the wheel. `This elevator `wheel may bes of any suitable diameter` according to the@ size and powerof the machine. Atthe front` part ofthe elevator wheel thebucketslare fully exposed, ibut atthe iback part a guard plate D, extends upward by its outer side "l and covers the`b1ickets,useeFig..1.` p To the under side :of the frame A, aplow K, is attached.` This `plowisprovided with"` a mold board and `land side as usual andit 1 is so placed relatively i with the `elevator` f wheel J, that its moldboard `g,jwill, asthe machine is moved alon i throw the earth` into the buckets p, of t `e"elevator wheel.

The plow K,\of courseilike the elevated@ wheel J, is made ofa size to correspond with the `size and powerofthemachiiie.

Around the wheela", on the axle E, of the` wheels C, a chain K', passes,said chainalso passing around a wheelw, `on a shaft] L",` .i some distance above the; axle E. Onitliis; i

shaft L, a toothed wheels, is `also placed, l

around which a chainMgpasses, said chain also `passing aroundatoothed wheel N,fat1 the inner side of the elevated `wheel `J Onf ioo y the shaftL, a loose pulley t, is placed which may be made to rotate with the shaft L,

when desired by means of a clutch u.V

Around the loose pulley t, a belt fu, passes, said belt also passing around a pulley fw, on the shaft I.

Around the frame A a railway O, is placed or secured. This railway is made to receive a series of cars p, which are provided with ltilting bodies see Figs. l and 2. The rail-way O, extends entirely around the frame A, and at each angle of the rail-way and consequently at each corner of the frame A, a turn-table Q, is placed in order to permit the cars to pass entirely around the machine. These turn-tables are each formed of a square frame, the sides b, of which correspond with the rails 0, of the rail-way, the sides b, being supported by arms d', and a circular base e', which is attached by a center bolt f, to a diagonal bar g, secured to the rails 0.

The operation of the'machine is as follows :w-The wheels C, are rotated and the machine conse uently propelled by the steam cylindersql'and the machine is guided by a person at the wheel l). As the machine moves along the plow K, throws the earth into the buckets p, and the elevator wheel J, is rotated from the shaft L, by the chain M, the shaft L, being rotated from the aXle E, by the chain K. As the wheel J, rotates the earth is carried up by the buckets p, the guard'plate D, retaining the earth therein until they reach a point nearly over the aXis of the elevator wheel when the earth is discharged by its own gravity into the bodies a', of the cars P. As each car becomes filled it is shoved along on the railway and an empty one takes its place, and when all the cars are filled the machine is propelled to the dumping place and each car dumped or its body tilted, it being remembered that the turn-tables Q, enable the cars to be moved around the corners or angles of the rail-way. The elevator wheel J, ma;7 be raised at any time by throwing the pulley t, in gear with the clutch a.

' Having thus described our invention what we claim as new and desire to secure by Let-- ters Patent, is-

1. The combination with a locomotive steamY engine of an earth elevator J, or its equivalent and suitable earth receptacles or their equivalents, so that the machine may be moved by its own power, under the guidance of an attendant, to the spot to be eX- cavated, then made to load itself and transport the load to the desired place for discharge in the manner herein set forth.

2. The combination with an excavating machine made as set forth, of a rail road track O, as shown, with or without the turn tables, as herein set forth.
